如何在react-native中过滤JavaScript对象

function filterObject(obj, condition) {
  // 创建一个空对象来存储过滤后的结果
  const filteredObj = {};

  // 遍历对象的属性
  for (let key in obj) {
    // 检查属性是否满足过滤条件
    if (condition(obj[key])) {
      // 如果满足条件，则将属性添加到过滤后的对象中
      filteredObj[key] = obj[key];
    }
  }

  // 返回过滤后的对象
  return filteredObj;
}

import React from 'react';
import { View, Button } from 'react-native';
import { filterObject } from './FilterUtils';

export default function App() {
  const obj = {
    name: 'John',
    age: 25,
    city: 'New York',
    country: 'USA'
  };

  const handleFilter = () => {
    const filteredObj = filterObject(obj, value => typeof value === 'string');
    console.log(filteredObj);
  };

  return (
    <View>
      <Button title="Filter Object" onPress={handleFilter} />
    </View>
  );
}
